While Haruhiro and the others were in Parano, a major incident was happening in Grimgar...

In a fast-moving world, a man hides his face beneath a mask, making his way towards Alterna alone...

"Am I being true to my own heart? Well, then there's no problem."

In addition to the new story telling of Ranta's struggles, "Feelings of the Mask," there is also "Please, Just a Little Longer," about the feelings of Manato, the volunteer soldier trainee who died before he could reach his goal, and "Let's Rest for Today," which depicts Yume and Shihoru's interactions with their respective masters at the guilds they joined. This volume contains four short stories, including those made as extras for the TV anime!
